Cavity spintronics explores light matter interactions at the interfacebetween spintronic and quantum phenomena. Until now, studies have focused onthe hybridization between ferromagnets and cavity photons.In this article, werealize antiferromagnetic cavity-magnon polaritons. The collective spin motionin single hematite crystals ({\alpha}-Fe2O3) hybridizes with 18 - 45 GHzmicrowave cavity photons with required specific symmetries. We showtheoretically and experimentally that the photon-magnon coupling in thecollinear phase is mediated by the dynamical Neel vector and the weak magneticmoment in the canted phase by measuring across the Morin transition. Thecoupling strength g is shown to scale with the anisotropy field in thecollinear phase and with the Dzyaloshinskii-Moriya field in the canted phase.We achieve a strong coupling regime both in canted (C > 25 at 300 K) andnoncolinear phases (C > 4 at 150 K) and thus coherent information exchange withantiferromagnets These results evidence a generic strategy to achievecavity-magnon polaritons in antiferromagnets for different symmetries, openingthe field of cavity spintronics to antiferromagnetic materials.
